QNEET-2013-Ph-1596: NEET 2013 Physics - Class 12 NEET-2013-Ph-1596 Solution: The primary of a transformer when connected to a dc battery of…
The primary of a transformer when connected to a dc battery of 10 Volt draws a current of 1 mA. The number of turns of the primary and secondary windings are 50 and 100 respectively. The voltage in the secondary and the current drawn by the circuit in the secondary are respectively 20 V and 2.0 mA 10 V and 0.5 mA Zero volt and therefore no current 20 V and 0.5 mA
Multiple Choice Options
- A 20 V and 2.0 mA
- B 10 V and 0.5 mA
- C Zero volt and therefore no current
- D 20 V and 0.5 mA
Step-by-Step Verified Solution
Transformer cannot work on dc.
